Instruction Manual
1. Description and range of application
Fully automatic condensate removal pump designed to remove condensate from furnace burners, gas
or oil condensing boilers, air conditioners, refrigeration display cabinets and de-humidifiers where
drainage by gravity is not possible.
WARNING: Regulations of water authorities or other relevant authorities must be
obeyed when condensate is being disposed of. Condensate from condensing
boilers being operated with standard heating-oil (not low on sulphur) may not be
disposed of into the canalization without being neutralized. This is also true for condensing
boiler systems exceeding 200 KW.
2. Technical Data
Motor power output: P2 = 80 Watt
Voltage: 230 V – 50 Hz
Nominal current: 0,6 A Operational

3. Scope of delivery
Ready to plug in pump with 2 metre power cable and signalling cable, inlet adapter, check valve and
instruction manual. The Neotech 360 – 6MT version also comes with discharge tubing (6m) which is to
be connected to the outlet side (check valve) which is supplied.
4. Installation and start up
WARNING: Read instructions completely prior to installing, operating or servicing the
pump! The installation may only be performed by a qualified person.
Check content for completeness and eventual damage prior to operation. Inform your dealer
immediately in case of any deficiency.
Never transport or remove the pump from the packaging by holding on to the
cable!
An orderly grounded mains supply and residual current circuit-breaker of max.
30mA disconnecting all phases is required for the operation of the pump.
Already existing outlets are to be checked for the existence of a residual current
circuit-breaker. Ensure that power cord is NOT plugged in when performing any
type of work on the pump.
4.1 Installation and inlet connection
The pump must be level (either on the floor or mounted on the wall) to ensure a proper operation.
The pump must be installed ensuring that it can not tilt and that it is properly
mounted!
The pump should be mounted close to the condensate drainage of the unit to be drained. The
connections from the unit to the pump are not included. Please ensure to use corrosion-resistant and
acid-resistant material when choosing the drainage pipes (e.g. PVC, PE, stainless-steel).
Condensate from condensing boilers is very aggressive and corrosive!
A standard high-temperature plastic wastewater tube (40mm) may directly be connected to one of the
three inlets by means of the supplied inlet adapter (see figure 2). Other pipes or tubing with a smaller
diameter may be safely fixed by running cable straps through the two holes in the adapter and firmly
tightening them.

adapter
Under no circumstances may pipes or tubes be inserted into the tank because this
may lead to pump failure since the integrated float switch may be blocked! Standard
condensing boilers are equipped with a siphon trap. This must in all cases
be filled with water prior to operation of the boiler and condensate pump. Failure to do so
may result in acidic gases reaching the pump and therefore destroying it!
